Twenty-one days: the maximum incubation period for Ebola Virus Disease. That means if you have come into contact with the virus but have no symptoms by day twenty two, then you are clear.

Forty two days: the incubation period x 2, and the period it takes for a country to be officially considered clear of the disease. If no new suspected cases are reported for 42 days, the outbreak is over.

Today, Wednesday 13th August 2014, is a big day for me ... it has been twenty-one days since I left Liberia, and for the first time I know beyond a doubt that I am Ebola-free. Not everyone is so lucky. In my first 14 days of incubation in the comfort of my Southampton home, the number of cases in Liberia more than doubled from 249 on 23rd July to 554 on 6th August. Of these cases, 294 people had died. The country is in a state of emergency, schools are closed, roads are blocked, communities are quarantined and attempts to bring the disease under control are being crippled by widespread fear.

So for another 21 days I am going to write a blog post every day to raise awareness of the grim challenge confronting Liberians, and to raise funds to support the Red Cross, who I work with collaboratively in my normal life as a PhD social researcher, and who are at the front line fighting the worst known Ebola outbreak in history.

How to stop an outbreak


What do we do when a deadly contagious disease grips a country?  On the assumption that Jack Bauer does not have all the answers (which, as a viewer of the TV series ‘24’, I willingly admit is tenuous), today we’re going to look at some of the elements that are critical to containing an outbreak of Ebola Virus Disease, which will lay the groundwork for understanding some of the problems that are being faced in Liberia and other West African countries:

1.       Trained and equipped medical staff – It’s vital that the cases of Ebola are managed properly.  This means barrier nursing techniques, including the wearing of protective clothing (such as masks, gloves, gowns, and goggles), using infection-control measures (such as complete equipment sterilisation and routine use of disinfectant), and isolating patients with Ebola from contact with unprotected persons.  In order to achieve this, the people need to be there in the first place, to be trained to recognise the symptoms of Ebola, to have the facility to test and confirm/disconfirm suspected cases, and to have the clinical environment and equipment that they need in order to achieve the standards above in the mean time.  With no exceptions.

2.       Containment – Early detection and isolation of cases is essential to stop Ebola spreading.  Ebola is NOT airborne (and don’t believe what you read to the contrary), and infection relies on the direct contact with bodily fluids from infected people who are displaying the symptoms of Ebola.  The risk of contagion increases the more advanced the disease is, so if you can identify people infected with Ebola in the early stages, not only does this increase their personal chances of survival, it also means you can isolate them and thus minimise the number of other people who come into contact with infected bodily fluids.

3.       Contact tracing – Once Ebola cases are identified, you need to list everyone who may have come into contact with contaminated bodily fluids and thus be at risk of contagion.  These ‘contacts’ must be traced, must be provided with information and counselling, and need to monitor their temperature and other signs of symptoms to ensure early detection.  I have heard it said that about one in ten contacts is likely to develop Ebola Virus Disease.

4.       Sensitisation – People need to know about the risk of Ebola - in perspective with other health risks that they may encounter, such as the much more common Malaria and Typhoid – and what to do about it if they or someone they care for experiences symptoms.  Something that was impressed upon me by the District Chairwoman of Bushrod Island in Monrovia is how fundamental education is to all aspects of life, peace and development in Liberia.  People need to understand how to identify the disease, how it is communicated, and what action to take if any symptoms are exhibited.  This needs to be common knowledge for Ebola to be contained.

5.       Cooperation – Perhaps this is the hardest battle to win.  People need to cooperate, 100%.  Staff need to adhere to the standards of hygiene that barrier nursing requires.  People who are suffering from Ebola-like symptoms need to subject themselves to the authority of medical agencies that require their containment.  Contacts need to be found, and to comply with the monitoring of their health.  Communities need to acknowledge that the disease exists and to support measures that are put in place to protect them.
A small disclaimer: I am not a public health expert.  Nevertheless, you may begin to imagine why agencies in the UK reassure us that an outbreak on the scale we are witnessing in Liberia and beyond would have less chance to take hold in the UK.  The world is not a fair and equal place.
